[snip: removed slurm.conf (49 lines)]

I don't have any experience of this kind of setup with a single user nor
in fact any setup not using the multifactor plugin.

However, you could have your java application choose the appropriate
QOS.  You might also find it worth having several different functional
users with, say, different numbers of shares.
